Sure no problem, I wont be raising my price this year by 5%. There is your 5% reduction.
Otherwise I take it off my services somewhere, if they complain tell em thats what they get for less.

This is exactly what I did several years ago when natural gas went out of sight. I was maintaining a heat treating company and went in with a new yearly contract with a 5% increase. The manager handed me a letter from their parent company asking all vendors to cut their prices by 10%. He said if I would keep my prices where they were he would sign it now...I signed for another year.
